IMPROVEMENT IN VAPOR-BURNERS.

Speciiicatiou forming part of Letters Patent No. 102,169, dated April19, 1870.

To all whom, it may concern,.-

Be it known that we, CHARLES E. SMITH and HENRY J. RICE, both ofColumbus, in the State of Ohio, have jointly invented certainImprovements in Vapor-Burners; and we do hereby declare that thefollowing, taken in .connection with the drawings which accomrangementand construction of the parts that all the gas is generated from ageneratingchamber located remotely from the burner and from the holesfor admitting atmospheric air by means of a special jet and without aidfrom the heat of the illuminating-burner; in a provision for regulatingthe flame and at the same time and by the same action regulating thesupply of oxygen from the atmosphere,

and in the position, construction, and means for regulating thegenerating-jet.

Figure 1 represents avapor-generatin g burner with our improvements, theparts being shown partially in section. Fig. 2 represents a modificationof the burner and adjacent parts. Fig. 3 is a top view of the tube andthe outletopening in said top.

A is the reservoir for oil or other gas-generatin g fluid, and which, byreason of the novelties of .our hereinafter-named devices, it is foundpracticable to locate in a plane much below that of the plane of themain burner, thereby diminishing greatly the risk of accidents,inasmuch` as the liquid can never rise a to the level of the plane, asit could (if unobstructed) in all the usual vapor-burners whosereservoirs are much higher than the burner.

B is the pipe, descending from the reservoir; C, a stop-cock therein; D,awick-tube forming, when connected with the other portions, a continuouspart thereof, but filled with wicking or other appropriate absorbent,which,

while it will arrest the onward flow of the liquid, will yet hold enoughto allow the generation in the generating-chamber E of all the gasrequired.

F is a thin partition, across the tubeat the forward end of thegenerating-chamber, and having in its center a small needle-hole as anoutlet for the gas as the same is generated.

G is asmall pipe, which we call a jet-pipe. It passes out from the underside of the generating-chamber, and both ends of it communicatetherewith, and at about its center, on its upper side, is a minuteheating or generating jet, H, the function o f which is to rapidlycreate gas, its position eminently fitting it for this'duty, as thellame or heat from it rises directly u nder, impinges upon, and runs uparound both sides ofthe generating-chamber. At the same time the rapidexpansion causes the gas as it is evolved to be driven in a livelycurrent up the pipe toward the distant burner with much the same effectas gas rises under the pressure of ordinary gas-works. In the jet-pipeG, I place a thumb-screw, I, or some equivalent device, for the purposeof regulating at option the jet in the pipe, or of cutting it entirelyoff.

The top of the tube upon which the burner is to be applied is closed bya partition, J, which has a small central hole, K, (see Fig. 3,) toreceive a pointed tapering valve, L, afxed toa cross-piece, M, in theburner. The burner N is arranged, as shown, to screw upon the top:of thegas-holder tube, and is provided, as seen in the drawings, with openingsO, to admit atmospheric air for the supply of oxygen, these holes beingnear the bottom of the burner. By this provision, in connection with thevalve, the screwing down of the burner toward the tube tends to close orpartially close gradually the valve-opening, and at the same time and inthe same degree to close or partially close the openings O, by whichmeans the supply of oxygen is increased or lessened to meet the demandfor it. By closing the valve-hole entirely the light may be eX-tinguished and the gas cut off. By turning the screw up or down theflame may be put 'high or low with as much facility as by anl ordinarycock, the ring P serving as a handle forthis purpose. By closing thevalve when the jet H is first lighted the vapor sufficient forilluminating purposes will be generated more quickly thanby'any otherburners known e realice to us, for the reason that the valve cuts offany escape ol gas during the process of heating.

Instead of screwing the burner upon the tube, as shown, the tube may bescrewed upon the burner; or a sleeve, Q, may surround the end of either,the otherbcing adapted to screw into or upon it, all as shown in Fig. 2.In this gure the cross-piece to which the tapering valve is secured isshown in cross-section. The principle of action is the same in bothfigures, the differences shown relating only to details.

By means of our construction no unsightly or cumbrous appliances areplaced upon the burner for the purpose of generating; but the burner andthe pipe Q, leading from it back to the generatingchamber, (which lattermay be iive feet or so distant from the burner,) present the appearanceof the ordinary gas pipes and burners.

By reason of the small needle-hole in partition F, in connection withthe long tube Q, between it and the burner and thc large oxygen-'holes O0, and the provision for enlarging or diminishing thc supply of oxygen,we can chamber having aI needle-hole orifice commu` nicating with a longconducting-pipe which connects such chamber with the burner,substantially as shown and described.

2. rlhe combination of the tube Q with the burner and its openings O andvalve, substantially as and for the purposes described.
